I could skip humans and sylvari as the first are quite generic anyway and the latter are new in Tyria and still shaping.
However the others:
The norn used to be solitary hunters, seekers of fame and glory, each hunter a one-man army basically as seen at the end of GW1 when only a couple join you to fight the Great Destroyer. What we have though is a pretty large population of them, scattered about Kryta mostly, evenly spread out in the three orders and in the Pact ... completely domesticated compared to their ancestors, wearing uniforms and following orders as part of a hierarchy ... if we went into it too much we could even imagine norn dishwashers, because hey someone has to do that job in the Pact as well.
the charr basically united into a great military machine, finally liberated Ascalon, an unstoppable force that was only stopped by the waking of the dragons. However NOW, as the threat doesn't seem that much serious anymore, where's the renewed drive to continue the campaign that was halted because of the Mursaat and that whole thing? Charr are predators, not some tame kittens. If not on the official front, there should at least be widespread discontent and conservative factions rising up among the charr, calling for war. Plus the same about the orders as with the norn.
the asura were forced to the surface by the Destroyers and basically Primordus. They immediately took control of their surroundings and assumed an intellectually superior position towards the other races. The others were inferior and not equal. Did that change? Their cultural stance should be supremacist, distrustful to the other races. Maybe they're not inclined for conquest but there should be a more defensive approach to dealing with bookahs. Maybe building a wall? Like the tengu did? Also it wouldn't be farfetched to picture the asura dreaming of being the masters of Tyria, as they are superior to everyone else.
